Gas Saving Gizmos & Gadgets

    "The POWERAID TBS concept was developed to enhance mid-range power, torque and fuel efficiency. The unique dyno-proven "Helix Bore" of the POWERAID TBS causes a spinning action of the incoming air-charge, as it passes through the throttle body. This extremely beneficial air-charge carries all the way into the combustion chamber, producing a super-atomized mixture, which produces tremendous gains in mid-range power and overall efficiency. This is the key element and horsepower success behind each POWERAID TBS."

    I don't understand how a Jacob's Ignition can improve gas mileage. It would seem to me that a little care would give just as good results such as replacing the plugs, wires, cap, rotor, points, condensers and so forth.

    As a reliable ignition system, Jacob's will do fine - but better gas mileage? Help me sort this out!

    I am the one who previously posted..."If it's too good to be true, it is to good to be true."
    Let's face the facts:If the auto manufacturers knew of any "Gas saving device" they would certainly be the first to get it and make it a "standard" part of their automobile.With auto manufacturers striving to meet E>P>A> guidelines..They would be more than happy to get and use same.example: if Ford or Chevrolet or Chrysler{woops,Mercedes}, could boost their mileage on "any of their new vehicles, it would be a major breakthrough for their product and sales would skyrocket. Yes, Honda has the "Insight" and it is not that well accepted, but boost the mileage of a Ford F150 by 4 to 5 more miles per gallon, or whatever, and they would have people standing in line for sales.

    I guarantee you that each auto manufacturer has 100s of employees working on fuel saving ideas, whether they are in engines, transmissions, wheel bearings, tires, etc. Heck, they will pay extra money for weight reduction just because every ounce of weight reduction translates into some fractional mpg increase.
  • Does anyone have any experience with the gas and diesel fuel additives called PRI-D and PRI-G? The ads I've seen tout the fuel storage benefits, but also mention fuel savings and longer engine life as a by-product. Thanks for any opinions.

    you will drive more conservatively, thus making the gimmick's claims come true. It "ain't the gadget, but the goon."

    The freer flowing exhaust and intakes a, along with thinner grade of oil (say 10w 30 to 5w 30)will help, after all the engine is an oversized air pump. Also drive like you have an raw egg between your foot and the gas pedal.

    Probably, driving like there's a raw egg between your foot and the pedal would provide most of the increase in fuel economy which would then be attributed to those mods. Try driving like the egg is there first before you spend seveal hundred bucks and you'll probably be suprised at how much of an improvement you see.

    I'm no Electrical Engineer (I'm a Mechanical instead), but when I talked to them a while back, (in reference to my car, 88 Camry V6), basically a good portion of spark energy is wasted below 3000 rpm (something with the circuits). The systems makes sure the full spark energy is consistent throughout the whole rev range. In addition, there is a control function, for two modes: economy and power, it is determined automatically. Also, each cylinder has it's own output to the "box", so using a sample, it measures against the determined values of spark energy & compensates for each individual cylinders.

    Talk to them (I found them informative and accurate, since by car's powerband does start at 3000 rpm.)

    made the mistake, no improvement, not even getting rated mpg for 4 cyl, 2.7L, tacoma dbl cab.
    figured no big deal 30 day warranty, hard to test and return in that period. waited too long, wasted my money. Going to take it out and throw away.

    1) Ankle regulator: special computer surgically implanted in right ankle that sends messages to right foot to carefully regulate use of the gas pedal.

    2) For manual transmission cars: Wrist regulator;another specially designed computer to be implanted in the right wrist that sends special signals to your hand to tell it to shift earlier and avoid frequent downshifts on highways.

    3) Check book regulator: Yet ANOTHER specially designed micro computer that is automatically activated whenever you open your checkbook at a car dealership and tells you to buy a more fuel efficient car.

    4) Feet: They normally come in pairs, and can save on fuel costs by allowing the user to walk when one's destination is not far away and it's nice out.

    5) Cruise control: Can be used to set speed at 60-65 mph, where fuel economy is optimal for most vehicles, rather than at the fuel sapping speeds of 75mph or greater that many who are on the lookout for mileage-improving accessories usually drive at.

    6)Backseat driving spouse, whose nagging instinct is automatically triggered by an electrical impulse whenever speeds exceed legal limits or sudden bouts of rampant accelaration occur.

    Those are great accessories! You can find parts numbers and prices at http://www.WeAreTheBorg/





  • I was as skeptical as anyone when I first saw the device, actually laughed at the student in class because it couldn't possibly work as claimed. Well to my surprise after installation some results were worth investigating. Started testing on our Clayton chassis dyno and recorded positive results in almost every vehicle we tested. Remember I am a racer and don't really worry about MPG. Saw some interesting HP gains on the dyno and lost them when we removed the device, remember this is all done in a 10 to 15 minute test period. Please don't bad mouth this device until you have actually tested it in your vehicle, don't forget to disconnect your battery to erase ECM memory so it can relearn the fuel trim curve faster.
  • Seeing HP gains on a chassis dyno still doesn't mean it works in the real world.

    1) Which vehicles did you test?
    2) Were they stock vehicles, since you're a 'racer'?
    3) Were the tests all conducted under the same conditions or was the humidity/pressure/temperature of the air varying from test to test?
    4) Were all of the engines and drive trains warmed up to the same operating temperatures each time?
    5) Were the vehicles you tested fuel injected or carbureted?
    6)What is an 'interesting HP' gain?

    The only reasons the tornado would work is if the engine has a very poorly designed intake system. There is no reason to 'swirl' air any more than what the intake runners are doing in most cases. Go sell snake-oil in another forum please!
  • IF they really worked the factorys would install them on all new cars. The factorys will stop at nothing to increase fuel enonomy 1 or 2 MPG.
  • scotianscotian Posts: 1,064
    Why then do they sacrifice the gains of an unrestricted air intake system for the reduced engine noise (while accelerating) that the stock airbox, etc., provide, with all their baffles, chambers, and twisty-curvy air paths?
  • i have 250k miles on my 94 accord i have stayed with the manufacturer recommended oil 5w30 dont burn a drop and its the best way i know how to save gas after your regular maintenance schedule it works on hondas
  • orcinmanorcinman Posts: 24
    As a starving college student, I was actually considering installing one of these gimics in my Elantra (the "tornado fuel saver"), however common sense and this forum have snapped me back into the realm of reality.

    Thanks guys. I wish Ithese gimmics worked, though.

    I see the claims for improved power/economy for aftermarket air filters, and ask, Has anyone you know attached a digital vacuum gauge ABOVE the throttle plate, and driven the vehicle at constant speeds on the same roads before and after the change? If the filter is really reducing restriction, there will be measurable vacuum above the throttle with the stock filter. Some years ago I used a clear plastic tube with a teaspoon of water for a manometer, and could not measure a vacuum above the throttle on my car at idle. The system did not allow me to test it under load with any equipment I had available at the time.

    This was in the late sixties when self proclaimed "experts" were turning their air cleaner covers up side down to "increase air flow". Some of us at the school did an experiment (U S Navy fleet training - mechanics, Davisville Rhode Island). We asked ten of our students if they would participate, and not look under their hoods. We had them fill their tanks every Monday and Thursday. We checked their oil that day, and either installed the covers correctly or turned over. They were told to drive normally, and report the amount of fuel, and miles on the car at each fill up. Without exception, the times when the cover was upside down for "more air" the fuel economy went down.

    The reasons most likely were:

    1. The carbuerators were less efficient when the air heating system did not work.
    2. The engines required more throttle to produce the same power when not fully warmed up but after choke opened.
    3. Some restriction was required to insure proper mixture with the carbuerator.

    I now tend to be very skeptical about claims for air filter devices. The manufacturers can reduce restriction if there is enough to matter, by simply increasing the size of the flter element. The only possible time there could be a problem IMO is wide open throttle.

    That problem actually did exist in the sixties on some Chevy II's. GM accidentally put air cleaner housings for 4 cylinder engines on some sixes. The tsb said to measure the diameter of the intake opening and replace with the appropriate part number if wrong.
